Disable Coverpage unconditionally in Outbound Fax Settings

In Settings --> Outbound Fax Settings --> Faxes Sent via Email There is the option "Omit cover page when email subject is blank" On or Off

We are evaluating the service now and intent to use MFP's to send the faxes which works, however the Ifax and Email configuration are shared on the devices from 2 different manufacturers. This means on our MFP for business reasons we have to leave a default subject line enabled which is carried through to the Ifax integration.

We will be billed for 2 pages instead of 1 on every fax sent from these machines as a result [Which is most of our outbound fax]
